This plugin allows for parts to have hollow insets that dont clip into other parts, ideal for engine nozzles, landing gear, air intakes, solar panel bays, and more. It is a standalone version of the depth mask module included in the Restock dll, which will be included in the next major Restock update along with the additon of depth masks to several stock parts. Works with KSP 1.11.

1. Add a depth mask mesh to your part model. It should cover up the hollow area you want to prevent clipping in, without sticking out. You can have multiple mask objects sharing the same name and they will all be used.
2. Mark the depth mask object with the Icon_Hidden tag to prevent it from showing in the VAB part picker.
3. Add a new ModuleDepthMask to your part config.
4. Add the name of your mask object in the maskTransform property.
5. (Optional) Add the name of the object you want to restrict the mask effect to in the bodyTransform property.

The depth mask will prevent any other parts from rendering behind it. Because of that, it should not be used on any kind of bay where other parts will be placed, or on any part you can look completely through. It also should "bubble" out above the hole you want to cover, otherwise it would be possible to see through it from the side. Also double check your normal direction, since the depth shader only works one way.

  MODULE
  {
    name = ModuleDepthMask
    maskTransform = mask
    bodyTransform = interior //Optional
  }

Mask meshes and configs for stock parts are included in ReStock
